Jackson was killed by a drunk driver on Feb. 4.
"I think a lot of guys that know [Jackson] in this locker room keep him alive in their heads and in their souls," Colts quarterback Andrew Luck said. "I certainly find myself thinking about him at different times and he was such a positive member of this team. We are so lucky and grateful to get to play football and he certainly took advantage of that. He was a joy and an honor to play with and be around.”
Colts players will be wearing an "EJ" sticker on their helmets on Sunday, and Indianapolis' coaching staff will don a pin with Jackson's initials.
The 1–2 Colts will host the Texans on Sunday at Lucas Oil Stadium in Indianapolis. Kickoff is slated for 1:00 p.m. ET.
